Visible light Assisted Photocatalytic Degradation of DIPA Using Fe-Zn/TiO2 Photocatalyst

Diisopropanolamine (DIPA) is washed out into water as a result of the process of carbon absorption, contributing to a high chemical oxygen demand (COD). Water with high COD content is not suitable to be treated by biological method and hence, Advanced Oxidation Processes (AOPs) are gaining more and...
